Black vs White paint
After many months searching classified ads website, I come up with a general observation that more expensive class A rvs usually have black paint and cheaper ones have white paint. Even for new RVs...

I've toured a couple of RV manufacturing facilities. Many builders buy the exterior fiberglass large sheets (gel coat, color coat, fiber glass, plywood backing and maybe foam insulation) and trim them down for what ever the current production run might be. Sheets are prefinished in what ever color the builder ordered, usually white but more rigs are coming off production in grays or browns. As such other than decals or other such embellishments no further work is needed and the coach is headed to the dealer after about 5 days of production build out. Fully painted rigs, add an additional three weeks to the process and a many, many hours of labor rolled into the cost to the next and future owners.
